The solution would be that if the customer comments out the line, the
software would be unusable without the license. You could also code the
licensing stuff in C and load it as a module. What kind of license do you
have in mind? A digital signature generated by OpenSSL or similar?
This brings another question to mind, regarding the Artistic License: if
you deliver Perl software with C-based modules (built with SWIG, XS, etc),
are you also required to distribute the source for that C code?
